The purpose of this study was to better understand teacher tensions in professional development. The population under study
was practicing mathematics teachers engaged in a week-long professional development institute. Data sources included observations,
interviews, and teacher products (such as registration forms, surveys, journals, and notebooks). The data were analyzed to
determine what tensions were evident in the institute and how those tensions arose. In this paper, we examine participants’
tensions in a professional development situation when their expectations did not match reality. We have done so by presenting
a theoretical model of professional development based on an instructional rhombus that illuminates the actual and applicatory
aspects of teachers’ professional development experiences. The main tensions expressed by the teachers were related to the
content and pedagogy of the institute. This study points toward the importance of teachers’ expectations in professional development. 相似文献

This study investigated the neural correlates of experts and novices during biological object pattern detection using an fMRI
approach in order to reveal the neural correlates of a biologist’s superior pattern discovery ability. Sixteen healthy male
participants (8 biologists and 8 non-biologists) volunteered for the study. Participants were shown fifteen series of organism
pictures and asked to detect patterns amid stimulus pictures. Primary findings showed significant activations in the right
middle temporal gyrus and inferior parietal lobule amongst participants in the biologist (expert) group. Interestingly, the
left superior temporal gyrus was activated in participants from the non-biologist (novice) group. These results suggested
that superior pattern discovery ability could be related to a functional facilitation of the parieto-temporal network, which
is particularly driven by the right middle temporal gyrus and inferior parietal lobule in addition to the recruitment of additional
brain regions. Furthermore, the functional facilitation of the network might actually pertain to high coherent processing
skills and visual working memory capacity. Hence, study results suggested that adept scientific thinking ability can be detected
by neuronal substrates, which may be used as criteria for developing and evaluating a brain-based science curriculum and test
instrument. 相似文献

There are a number of theoretical perspectives established for studying adult participation in education, but they are seldom examined together in single studies; neither are participants and non-participants examined simultaneously. This study examines the relative power of the major perspectives in distinguishing between and predicting participants and non-participants. Secondary school teachers who were participating or not participating in continuing professional education programmes were taken as target respondents. Results show that the theoretical perspectives of situations, dispositions, attitudes and beliefs in continuing professional education, and social norms and pressure, do not discriminate teacher participants and non-participants and are therefore not good predictors of the participation status of teachers. Only a few factors in the perspectives of motivations and socio-economic background are significant and meaningful in distinguishing the two teacher groups and in predicting participation status. 相似文献

This paper investigates the problem of global exponential stability for neutral systems with interval time varying delays and nonlinear perturbations. It is assumed that the state delay belongs to a given interval, which means that both the lower and upper bounds of the time-varying delay are available. The uncertainties under consideration are norm-bounded. Based on the Lyapunov–Krasovskii stability theory, delay-partitioning technique and lower bounds lemma, less conservative delay-dependent exponential stability criteria are derived in terms of linear matrix inequalities (LMIs) with fewer decision variables than the existing ones. Numerical examples are given to show the effectiveness of the proposed method. 相似文献

This study examines cross-national and cross-media differences in framing, particularly regarding the salience of collectivistic storytelling, based on the US and Korean newspapers and blogs about the Virginia Tech campus shooting incident. Although collectivistic storytelling is a common practice of news domestication, the degree of its salience is affected by a nation's orientation toward collectivism. Cross-media level of difference also exists because journalistic perspectives and the public's interpretation of those perspectives, as reflected in newspapers and blogs, are different. Findings indicate that while there are some consistent framing patterns, the degree of collectivism was different between the two nations and between the two media. 相似文献

The aims of this study were to determine how custom-fit compression shorts affect athletic performance and to examine the mechanical properties of the shorts. Ten male and 10 female track athletes on a university's nationally competitive track team, specializing in sprint or jump events, participated in the study. Testing utilized the compression shorts with loose-fitting gym shorts as the control garment. Several significant effects were revealed for the custom-fit compressive garment. Although 60 m sprint time was not affected, hip flexion angle was reduced. Skin temperature increased more and at a faster rate during a warm-up protocol. Muscle oscillation was decreased during vertical jump landing. Countermovement vertical jump height increased when the participants were wearing the custom-fit compression garment. In materials testing, the elasticity of the compressive garment provides increased flexion and extension torque at the end range of extension and flexion, respectively, and may assist the hamstrings in controlling the leg at the end of the swing phase in sprinting. The compressive garment significantly reduced impact force by 27% compared with American football pants alone. Through various mechanisms, these findings may translate into an effect on athletic performance and a reduction in injuries. 相似文献

The relevancy of public libraries is often called into question, with some saying that library services have been or will be displaced by, among other things, new media such as social media. This study tested this displacement hypothesis with survey data collected from three nations (the U.S.: N = 879; South Korea: N = 700; and Singapore: N = 987). Ordinal regressions were used to investigate the relationship between the use of social media and nine public library services, taking into account individual demographic differences. The results show that for all three nations, social media use has significant complementary relationships with all nine library services examined. Computer and information literacy training showed the largest effect size. However, signs of displacement effects were observed in the odds ratio statistics, particularly among daily social media users and in reference services, library visits, and time spent in the library, suggesting that where displacement is concerned, these areas warrant extra attention. 相似文献

This study investigates networked framing of terrorism news in Twitter by distinguishing three proximity effects (geographic, social, and temporal proximity) on audience and media institutional frames (i.e., episodic/thematic and space frames), based on construal-level theory. An analysis of tweets during the Boston Marathon bombing and the Brussels Airport attack finds that institutional and audience frames show similarity but do not always converge on Twitter. Similarities in the audience and institutional frames are attributed to a universal human tendency for social categorization, inherent in the minds of not only ordinary citizens but also journalists. Proximity effects, however, were more salient on audience frames than on institutional frames. 相似文献
